[Unity] Auto-save scene on play (to prevent work-loss on crash)

Denzil

Hi!

For those of you who use Unity, I am sure you have encountered the frustrations of having Unity crash on you - due to something you did, or due to a bug in Unity. Either way, if you have forgotten to save your scene in a while, you may have lost a significant amount of work. This script will help minimize the risk a bit by auto-saving your scene when you press play (assuming you play-test a lot like me, you will rarely lose any work again). Simply add it to an object that is in all your scenes:

#if UNITY_EDITOR
using UnityEngine;
using UnityEditor;


[InitializeOnLoad]
public class AutosaveOnRun: ScriptableObject
{
	static AutosaveOnRun()
	{
		EditorApplication.playmodeStateChanged = () =>
		{
			if(EditorApplication.isPlayingOrWillChangePlaymode && !EditorApplication.isPlaying)
			{
				Debug.Log("Auto-Saving scene before entering Play mode: " + EditorApplication.currentScene);
				
				EditorApplication.SaveScene();
				EditorApplication.SaveAssets();
			}
		};
	}
}
#endif

lol.
Me and @tbulford were saying the other day that we wish unity would do this... and now it does
THANK YOU

Oh nice.

You should consider releasing this one the unity asset store as a free script.

@tbulfrod I actually copied from a Unity answers... answer. Just added the #if so that it doesn't compile in actual builds (as it can't and will give an error). I couldn't not share it with you guys. I nearly scratched my own eyeballs out when I lost some work. again. So I opted to instead keep my eyes, and look for a solution instead.
